TOI 700 e is the latest planetary discovery in this solar system. In 2020, three other planets were also found orbiting the star TOI 700. Named TOI 700 b, TOI 700 c and TOI 700 d, they too are believed to orbit within the so-called optimistic habitable zone.
TOI 700 is a red dwarf 101.4 light-years away from Earth located in the Dorado constellation that hosts TOI 700 d, the first Earth-sized exoplanet in the habitable zone discovered by the Transiting Exoplanet Survey Satellite.
TOI-700 d is a super Earth exoplanet that orbits an M-type star. Its mass is 1.25 Earths, it takes 37.4 days to complete one orbit of its star, and is 0.1633 AU from its star. Its discovery was announced in 2020.

Earth, an Unfit planet for survival - Scientific reasons & Truths | Trees | Deforestation makes the earth unfit to survival | We are at risk of Losing our earth by destroying trees
A research says Earth's oxygen is projected to run out in a billion years, you know Why? because of we are slowly harvesting the heart of oxygen (Trees) from this earth.
We must realize the fact that trees act as giant bulwarks to provide us with the oxygen we need to survive and protect us from many natural disasters.
Trees, a great boon given by nature to this earth and the life on it.
In this video, we have narrated about trees and its origin, history, how connected with the life of living things in the earth, influence to environmental changes and producing oxygen, and what is halogen?, different groups of plants and fungi in the earth. Moreover, Also we have deeply described about the impact of cutting down trees on the ecosystem and our future generation.
We can give what matters most to our future generation who need it most. Because a first step of our endeavor for saving trees can give our generation a healthy and long life.

Truth Behind Animals Sent To Space,
Laika was a normal street dog in Russian country, The aim was to find out how long a dog can survive in space. On 3 November 1957 russians launched Laika into space inside a spacecraft named Sputnik-2. It was a one way ticket for laika because there was no way to bring her back to Earth. Space has no boundaries. You must admit that there is something incredibly attractive and mysterious in this dark surrounding our earth, Some of these interesting facts are amazing yet terrifying at the same time. i am really feld bad about the innocent animals that really what happend to them in the history.

Hi everyone,
We think we know everything about our home planet, but we couldn’t be more wrong. Scientists have already discovered a lot about the Universe, but they believe there is still much more to learn about our planet. You’ll be amazed when you find out how much you have yet to learn about our home planet, let’s start with 45 unknown earth facts.
Summary:
1. There weren't always several continents
2. Some 300 million years ago, there was just one continent. A massive
supercontinent called Pangaea. And thus, there was just one giant sea,
called Panthalassa.
3. Our solar system is 4.57 billion years old.
4. Researches calculate that the earth is approximately 4.54 billion years old,
that is insanely old.
5. The earth is approximately 93 million miles (150million kilometres) from
the Sun. It makes about 8 minutes and 19 seconds for sunlight to reach our
planet.
6. Earth's gravity isn't uniform
7. Because of imbalance gravity/centrifugal force at the equator coupled with
the speed that the earth is spinning. Our planet is not a perfect sphere. it is
slightly bulging out in the middle.
9. Our poles switch. our planet has settled into a pattern of a pole reversal
about every 2,00,000 to 3,00,000 years.
10.The circumference of the globe is 24,901 miles (40,075 kilometres)
11.The earth isn't just spinning in place, its zipping around the sun at a rate of
67,000miles (107.826 kilometres) per hour.
12. Earth's icy times
13. In the past, sea levels were very different
14.The days are getting longer.
15.At the equator, you would weigh less than if standing at one of the poles.
16.Depending on where you are on the globe, you could be spinning through
the space at just over 1,000 miles per hour.
17.Hudson Bay, Canada, has lower gravity than other regions of the earth.
18.The Pacific Ocean is huge; it covers an area of about 59 million square
miles (155 million square kilometres) and containing more than the half of
the free water on earth.
21.Coral reefs support the most species per unit. Area of any of the planet's
ecosystems, rivalling rain forests.
22.Researchers believe that at one point, we had two moons. our second moon would have been about 750 miles orbited the earth in the past.
23.We always see the same side of the Moon, no matter where we stand on Earth.
24.The moon is not Earth's only companion
25.The lowest point on earth that is ' on land' is the dead sea
26.The driest place on Earth
27.El Aziziya, Libya holds the record for the hottest place on earth. According
to NASA, it hit 136 degrees Fahrenheit (57.8 degrees Celsius) on
September 13, 1922.
28.The lowest temperature ever recorded on earth came from Russia's Vostok station
29.The calm before the storm
30.A single stroke of lightning can heat the air to around 54,000 degrees
31.Our sun has a voracious appetite
32.Only 5% of the universe is visible from Earth.
33.Earth is one of the four terrestrial planets: like Mercury, Venus, and Mars. It is rocky at the surface.
34.In our solar system that are 4 planets known as gas giants: Jupiter, Saturn, Uranus & Neptune.
35. Mercury & Venus are the only 2 planets in our solar system that have no moons.
37.The hottest planet in the solar system is Venus with an average temperature
of 464 degree Celsius
38. The coldest planet in the solar system is Pluto with an average
temperature of -225 degree Celsius.
39.The Sun weighs about 330,000 times more than Earth.
41.Pluto is smaller than the United States

What If There was No Sunlight to Earth?
If there was no sunlight reaching Earth, the consequences would be catastrophic for life as we know it. Sunlight is essential for numerous biological and physical processes on our planet. Here are some of the major impacts:
Loss of Photosynthesis: Sunlight is crucial for photosynthesis, the process by which plants and some bacteria convert light energy into chemical energy to produce food. Without sunlight, photosynthetic organisms would be unable to survive, leading to the collapse of the entire food chain.
Ecosystem Disruption: The extinction of plants would result in the extinction of herbivores that rely on them for sustenance. This, in turn, would affect carnivores and other predators in the ecosystem. The disruption would likely cause a mass extinction event.
Temperature Drop: The Sun's energy is responsible for heating the Earth's surface. Without sunlight, the planet would rapidly cool down. The temperature drop would be drastic, leading to extremely cold conditions, especially in areas away from geothermal heat sources.
Loss of Atmospheric Circulation: Sunlight plays a crucial role in driving atmospheric circulation, which includes the formation of weather patterns and wind currents. Without sunlight, the atmosphere would become stagnant, resulting in the loss of weather systems and wind patterns.
Darkness: Obviously, the absence of sunlight would plunge Earth into darkness. The sky would be devoid of the typical blue color, and daylight-dependent activities would become impossible.
Disruption of the Water Cycle: Sunlight provides the energy required for the evaporation of water, which is an essential component of the water cycle. Without sunlight, the water cycle would slow down significantly, affecting rainfall patterns, freshwater availability, and overall climate stability.
Impact on Human Life: Humans, along with other organisms, depend on sunlight for vitamin D synthesis, which is crucial for bone health. The absence of sunlight would lead to widespread vitamin D deficiencies, resulting in health issues. Additionally, agriculture, which heavily relies on sunlight, would be severely affected, leading to food shortages and famine.

டயனோசர்களின் தோற்றமும் மறைவும் | Evolution of dinosaurs #dinosaur #vaanveli #extinction
Origins and Early Evolution
Triassic Period (approximately 250-201 million years ago):
Archosaurs: Dinosaurs evolved from a group of reptiles called archosaurs. Early archosaurs appeared in the Triassic period, and from them, the first dinosaurs emerged.
Eoraptor and Herrerasaurus: Among the earliest known dinosaurs are Eoraptor and Herrerasaurus, small bipedal predators from South America, dating back to around 231 million years ago.
Major Dinosaur Clades
Jurassic Period (approximately 201-145 million years ago):
Saurischia: This group includes theropods (bipedal carnivores like Tyrannosaurus rex) and sauropodomorphs (long-necked herbivores like Brachiosaurus).
Ornithischia: This diverse group of herbivorous dinosaurs includes stegosaurs (Stegosaurus), ankylosaurs (Ankylosaurus), and hadrosaurs (duck-billed dinosaurs).
Cretaceous Period (approximately 145-66 million years ago):
Diversification: Dinosaurs reached their peak diversity during the Cretaceous. Major groups like ceratopsians (Triceratops) and theropods, which later gave rise to birds, flourished.
Bird Evolution: Theropod dinosaurs, particularly a group called maniraptorans, evolved into birds. The famous Archaeopteryx is often cited as a transitional fossil between non-avian dinosaurs and birds.
Extinction and Legacy
Cretaceous-Paleogene (K-Pg) Extinction Event (approximately 66 million years ago):
Mass Extinction: A catastrophic event, likely an asteroid impact, led to the extinction of most dinosaur species. However, avian dinosaurs (birds) survived and are their direct descendants.
Climate Change: The impact and subsequent environmental changes caused by the impact led to a drastic cooling of the Earth's climate. This would have disrupted ecosystems, causing a decline in plant life, which, in turn, would have affected herbivorous dinosaurs and the predators that relied on them.
Mass Extinction: The combination of factors, including extreme temperature fluctuations, lack of sunlight, and ecological disruption, likely resulted in a mass extinction event. Many species, including the non-avian dinosaurs, went extinct during this time.
Surviving Species: While the non-avian dinosaurs went extinct, some groups of animals, such as birds, small mammals, and reptiles, managed to survive and eventually evolve into the diverse life forms we see today. Birds are the only living descendants of the dinosaur lineage.
Adaptive Radiation: Dinosaurs adapted to various ecological niches, leading to a wide range of forms and sizes, from tiny, feathered theropods to enormous sauropods.
Feathers and Flight: Many theropods had feathers, initially for insulation or display, which eventually evolved for flight in the ancestors of birds.
Social Behavior: Evidence of social behavior, such as nesting sites and herd movement, suggests complex behaviors among some dinosaur species.

Hi,
பிரமீடை காட்டியது ஏலியனா இல்ல மனிதனா ? The Pyramid vs Aliens
Pyramid Shape: The most distinctive feature of pyramid architecture is the use of a pyramid shape or form in the design of buildings or structures. This shape is characterized by a polygonal base and triangular sides that slope upward to a single point or apex.
Historical Inspiration: Pyramid architecture often draws inspiration from the ancient pyramids of Egypt, particularly the Great Pyramid of Giza. These ancient structures were built as tombs for pharaohs and have a well-known stepped-pyramid design.
Symbolism: Pyramids have symbolic significance in various cultures. In addition to their historical use as tombs, they can represent concepts such as stability, endurance, and ascension.
Modern Interpretations: While ancient pyramids were constructed using massive stone blocks, modern pyramid architecture may use a wide range of materials, including glass, steel, concrete, and more. Architects and designers may incorporate pyramid-like shapes or elements into contemporary buildings for aesthetic or symbolic purposes.
Pyramid Roof: Some buildings have pyramid-shaped roofs or spires, which can give them a distinct appearance. These roofs can be found in a variety of architectural styles, from ancient to modern.
Functionality: Pyramid architecture can be applied to various types of buildings, not just tombs. Modern architects may use pyramid designs for residential homes, commercial buildings, museums, and other structures.
Cultural Variations: Different cultures have their interpretations of pyramid architecture. For example, Mesoamerican civilizations like the Maya and Aztec built pyramidal temples. These structures often have stepped pyramid designs and serve religious or ceremonial purposes.
Sustainability: Pyramid architecture can also be associated with sustainable design principles. The shape of a pyramid can be efficient for natural ventilation and energy conservation, making it a consideration in green building practices.

Hi All,
The Chicxulub asteroid is a term commonly used to refer to the massive asteroid or comet impact that occurred approximately 66 million years ago. This impact is believed to be the primary cause of the Cretaceous-Paleogene (K-Pg) extinction event, which resulted in the extinction of about 75% of plant and animal species on Earth, including the dinosaurs.
The impact site is located near the town of Chicxulub in Mexico's Yucatan Peninsula. The asteroid or comet that struck Earth was estimated to be about 6 miles (10 kilometers) in diameter. The impact released an enormous amount of energy, equivalent to billions of atomic bombs, causing widespread devastation.
The impact triggered a chain of catastrophic events, including massive earthquakes, tsunamis, and wildfires. It also released an enormous amount of dust, soot, and vaporized rock into the atmosphere, blocking sunlight and causing a global cooling effect. The reduced sunlight led to a significant decrease in photosynthesis, disrupting the food chain and causing the extinction of many plant and animal species.
The Chicxulub impact left a distinct crater, which was discovered in the early 1990s through geological surveys and subsequent drilling. The crater measures approximately 93 miles (150 kilometers) in diameter and is buried beneath layers of sediment.
The study of the Chicxulub impact has provided valuable insights into the dynamics of large asteroid or comet impacts and their potential effects on Earth's ecosystems. It has also contributed to our understanding of the history of life on Earth and the mechanisms of mass extinctions.
The Chicxulub impactor, also known as the Chicxulub asteroid or the K-Pg asteroid, refers to a massive asteroid or comet that is believed to have struck the Earth approximately 66 million years ago. The impact of this asteroid is considered to be a significant event in Earth's history as it is widely associated with the mass extinction event that led to the demise of the dinosaurs and many other species.
Here are some key details about the Chicxulub impactor:
Size and Impact: The Chicxulub impactor is estimated to have been about 6 to 9 miles (10 to 15 kilometers) in diameter. When it struck the Earth, it unleashed an immense amount of energy, equivalent to billions of nuclear bombs.
Location: The impact site is located near the town of Chicxulub in the Yucatan Peninsula of modern-day Mexico. The region is known for a prominent crater, known as the Chicxulub crater, which was discovered in the early 1990s.
Extinction Event: The impact of the Chicxulub asteroid is widely believed to have caused or significantly contributed to the Cretaceous-Paleogene (K-Pg) mass extinction event. This event led to the extinction of approximately 75% of all species on Earth, including non-avian dinosaurs.
Environmental Effects: The impact generated a massive amount of heat, causing widespread wildfires and releasing enormous quantities of dust, ash, and gases into the atmosphere. This resulted in a global climate change event, with a significant drop in temperature and a reduction in sunlight reaching the Earth's surface. These changes severely disrupted ecosystems and led to the extinction of many plant and animal species.
Crater Formation: The impact created a crater that is approximately 93 miles (150 kilometers) in diameter and 12 miles (20 kilometers) in depth. Over time, geological processes and erosion have modified the original structure, but the remnants of the crater are still visible.
Discovery and Confirmation: The presence of a large impact crater in the Yucatan Peninsula was first proposed in the late 1970s. In the early 1990s, scientific drilling in the region provided evidence supporting the hypothesis that the Chicxulub impactor was responsible for the K-Pg mass extinction event.
